CVE-2026-42233: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in n8n-io n8n
A SQL injection vulnerability exists in the Oracle Database node's select operation in n8n versions prior to 1.123.32, 2.17.4, and 2.18.1. The flaw allows user-controlled input passed into the Limit field via expressions to be directly interpolated into SQL queries without proper sanitization or parameterization. This can enable an attacker to inject arbitrary SQL commands and potentially exfiltrate data from the connected Oracle database. The issue has been addressed in the specified patched versions.
AI Analysis
Technical Summary
n8n, an open source workflow automation platform, contained a SQL injection vulnerability (CWE-89) in its Oracle Database node's select operation. Specifically, user input passed into the Limit field was not sanitized or parameterized before being included in SQL queries. This vulnerability affected versions prior to 1.123.32, 2.17.4, and 2.18.1. Exploitation requires user-controlled input, such as from a webhook, to be passed into the Limit field, allowing arbitrary SQL injection and data exfiltration from the Oracle database. The vulnerability has been patched in the mentioned versions.
Potential Impact
Successful exploitation allows an attacker with the ability to influence the Limit field input to execute arbitrary SQL commands on the connected Oracle database. This can lead to unauthorized data disclosure. The CVSS 4.0 base score is 5.3 (medium severity), reflecting network attack vector, low attack complexity, partial privileges required, no user interaction, and high scope and impact on integrity and availability.
Mitigation Recommendations
This vulnerability is patched in n8n versions 1.123.32, 2.17.4, and 2.18.1. Users should upgrade to these or later versions to remediate the issue. No vendor advisory content contradicts this; therefore, upgrading is the recommended mitigation. Patch status is confirmed by the version information provided.
